Indispensable presence
Always ahead of the field
Nippon Nozzle Co., Ltd. first succeeded in manufacturing spinnerets for rayon in 1930. It was
the very first company to produce spinnerets in Japan.
We have been working relentlessly to explore the indefinite possibilities of synthetic fibers.
We believe in innovation and flexibility. We pride ourselves in being able to adapt to market
conditions, as well as industry trends.
With over 80 years of experience, we have built a reputation for quality and excellence that
has become our hallmark. We have received high commendations from many customers and
have developed strong relationships with them based on trust and commitment.
Pioneer in Spinneret
A pioneer making contributions
in different industries
Today we see the indefinite possibilities of synthetic fibers, the excellent characteristics of
fibers are being used in a wide range of products such as the materials for aircraft, vehicle,
and construction field.
Global perspectives are called for in achieving the technology required in spinneret
manufacturing. Many of our products are already playing major roles in electronics, vehicle
components, and medical industries.
Our high precision manufacturing technology is attracting strong interest from other
industries and is applied to parts like soldering on PCBs, ink jet devices
for printers, automobile fuel injectors where accurate performance is required.
We are also actively finding ways to make contributions to society, whether in the form of
recycling, the development of products needed for the elderly care and research of new
materials. No longer confined by the traditional function of fiber, Nippon Nozzle expects its
expertise can play an even larger role in different industries in the future.

SYNTHETIC FIBER SPINNERETS
SPINNERETS FOR WET SPINNING
Wet spinning is used for polymers that need to be dissolved in a solvent first. The spinneret is immersed in tanks containing the
solvent into which the filaments are extruded. Acrylic, vinyl, rayon are produced by this method.
Furthermore, Carbon Fiber can also be produced by this process. Carbon Fiber is a fibrous carbon material and can be
classified into PAN-based, pitch-based and rayon-based. Among them, PAN-based carbon fiber is in the largest production
and best used in volume. PAN type carbon fiber, which makes up 90% of the total market, is produced by carbonization of
PAN precursor (PAN: Polyacrylonitrile) and has high tensile strength and high elastic modulus. Actually, Carbon Fiber can be
produced by both wet and dry-wet spinning methods. Wet spinning is more common. The spinneret is submerged in a chemical
bath and when the filaments emerge, they precipitate from solution and solidify. In comparison with dry-wet spinning, the
spinnerets used usually have more holes.

SPINNERETS FOR DRY SPINNING
In dry spinning, the fiber-forming substance is melted for extrusion through the spinneret. Solidification is
then achieved by evaporating the solvent in a stream of air or inert gas. Acetate, acrylic and spandex can be
produced by this method

SYNTHETIC FIBER SPINNERETS
SPINNERETS FOR DRY-WET SPINNING
Carbon fiber produced by the dry-wet spinning method generally has higher tensile strength and elastic modulus than
its wet spinning counterpart.
As a result, it’s extensively used in structural material composites applied in aerospace and industrial field. In dry-wet
spinning, the filaments first pass through air and then are cooled further in a liquid bath. Because of the special spinning
conditions, spinnerets are usually larger in size and are made of less expensive materials such as stainless steel.

SPINNERETS FOR MELT SPINNING
In melt spinning, the fiber-forming substance is melted for extrusion through the spinneret and then directly
solidified by cooling. Nylon, Olefin, and Polyester are produced in this manner.
Shaped fibers can be made by using spinnerets with non-round holes. Let us know your requirements and we can

MELT BLOWN / SPUNBOND / T-DIE
Melt Blown / T-DIE
MB is a one-step process in which high-velocity air blows a molten thermoplastic resin from an extruder die tip onto a conveyor
screen to form a fine fibrous and self-bonding web.
This process is unique because it is used almost exclusively to produce microfibers that generally have diameters in the range of
2 to 4 µm, although they may be as small as 1 µm or below.

Detergent S-BACK N
With our abundant experience and years of research, we developed the Detergent S-BACK N for
washing spinning spinnerets in synthetic fiber industry. Traditional way of spinneret cleaning is to use
heat treatment or triethylene glycol. However, as the variety of the additives to the polymer increases,
it becomes harder to wash all the spinnerets cleanly, especially the inside of tiny holes. The way of
spinneret cleaning process is changing. Detergent S-BACK N makes solution to your requirement.
